Mostly non-fiction story.
My woman led a diverse and active sex life starting at a youngish age. I get highly aroused when, on occasion, she relates some of these adventures. The story below happened when the summer after her sophomore year at University in Tennesse a few months after her 19th birthday.
Go back about 25 years.
Steve and Sue had decided, on the spur of the moment, to hitchhike to the Blue Ridge Mtns and find a trail to hike for a couple days. All they had with them were backpacks with a sleeping bag. Stupidly, they only had a couple cans of food and some bread, and some good grass. They did have a small canteen.
Steve and Sue were mainly just friends at school and had never really "dated". Sue had a couple regulars as dating material during the year.
After they arrived at a logical jumping off point for the trail, they started the hike. It was about an hour or two into the hike that they ran into 2 other kindred couples. They were better equipped for overnight camping so it made sense to join forces with them.
By early afternoon is was hot. In the past hour they had only one other group.
"Let's all strip and hike nude in the hot weather" declared one of the other guys. The only shy one in the group was Steve. He didn't want to be the odd man out, so joined the crowd and, like the others, was only left with his hiking boots on.
